Definitions

  • the above referenced patents refer to a technology for inline skates, ice skates and ski bindings.
  • the technology improves the ability for ice skaters, inline skaters and skiers to shift the center of gravity along the length of the foot, from heel to toe, with an even pressure, thereby improving skating/skiing comfort and performance.
  • the technology includes a chassis comprising at least one upper chassis section and at least one lower chassis section.
  • the chassis sections include at least one first contact surface and at least one second contact surface, wherein at least one of the contact surfaces is curved or partially curved.
  • the contact surfaces are arranged so that the chassis sections can pivot in relation to each other in the longitudinal direction, and so that at least a portion of a curved contact surface is in contact with at least a portion of another contact surface.
  • the upper chassis section and the lower chassis section are interconnected by a coupling means that has both a coupling and a spring back effect.
  • the type of coupling means is non exhaustive in the patent applications, and can be of any kind as long as it has the two mentioned characteristics. The present application is for a specific type of such coupling means.
  • Fig. 1 a-c are cross sectional side views of a chassis schematically illustrating an embodiment of the coupling means 5, and its function.
  • Fig. 1 a shows the upper chassis 1 rocking (being tilted) backward with respect to the lower chassis 2.
  • Fig. 1 b shows the upper chassis 1 and the lower chassis 2 in their neutral position.
  • Fig 1 c shows the upper chassis 1 rocking forward with respect to the lower chassis 2.
  • the coupling means 5 is arranged in a chassis 20 designed for ice-skating.
  • the chassis 20 and the coupling means 5 can be designed for inline (roller) skating or for ski bindings.
  • the chassis 20 comprises at least an upper chassis section 1 that is connected to at least a lower chassis section 2 through a coupling means 5 in accordance with the present invention.
  • the upper chassis section 1 includes at least a first contact surface 3 and the lower chassis section 2 includes at least a second contact surface 4.
  • the first contact surface 3 and the second contact surface 4 are arranged so that they are facing each other.
  • the first contact surface 3 is curved and the second contact surface 4 is flat.
  • the coupling means 5 includes at least one spring back component 6, e.g. a leaf spring, running in the chassis 20 longitudinal direction.
  • the spring back component 6 is arranged between the first contact surface 3 and the second contact surface 4.
  • the spring back component 6 includes a third contact surface 8 and a fourth contact surface 9.
  • the spring back component 6 can be made of any suitable material such as e.g. metal, plastic, rubber, composite or wood, or some combination of such materials.
  • the spring back component 6 is held in place in relation to the lower chassis section 2 at its front and back end by suitable holding means 10.
  • the holding means 10 are formed by recesses arranged in a front end and a back end protuberance of the lower chassis section 2, respectively.
  • the lower chassis 2 further includes a number of grooves 11 along its contact surface 4.
  • the grooves 11 are arranged at predefined positions along the lower chassis section 2 (forming a position indicator, or a gauge scale). Further, each groove 11 is arranged extending perpendicularly with respect to the lower chassis section's 2 longitudinal direction.
  • the upper chassis section 1 includes a number of perpendicular holes 12. Each hole 12 is arranged at a position corresponding to the position of a respective groove 11 of the lower chassis section 2.
  • the coupling means 5 includes at least one sprint/axis 13, which is arranged extending through at least one of the holes 12. This is further illustrated in Fig. 2 , which is a cross sectional front view of the chassis 20.
  • the sprint/axis 13 is further arranged below the spring back component 6.
  • the embodiment of Fig. 1a - c comprises two sprints/axes 13 arranged in a respective hole 12. In this embodiment the sprint/axis 13 extends through at least the width of the upper chassis 1. In alternative embodiments the sprint/axis 13 may just partly be extended through the upper chassis section 1.
  • each groove 11 is to make room for a sprint/axis 13 to vertically move freely in relation to the lower chassis 2 as the upper chassis section and the lower chassis section are rocked with respect to each other.
  • the coupling means' 5 coupling effect is enabled through the sprint/axis 13 running through the holes 12 in the upper chassis 1, through the grooves 11 in the lower chassis 2, and under the spring back component 6, that is held in place to the lower chassis section 3 by the holding means 10.
  • the coupling means' 5 spring back effect is enabled as a curved contact surface rocks/rolls against another contact surface, as the sprint/axis 13, which is attached to the holes 12 in the upper chassis section, lifts the spring back component 6 from a portion of the second contact surface 4, thereby bending it in relation to its neutral shape (initial shape), under accumulation of energy.
  • the spring back component's 6 spring back effect is achieved as it strives to return to its neutral position, releasing the accumulated energy.
  • the spring back components 6 neutral shape is straight. In alternative embodiments the spring back components 6 neutral shape can be curved.
  • Fig. 1 d the different hole positions 12 a-i (the number of holes can in embodiments of the invention be selected to be higher or lower than shown here) of the exemplifying embodiment are shown in more detail.
  • the sprints/axes 13 are not shown.
  • the hardness of the spring back functionality can be adjusted by placing the sprints/axis' 13 in the different positions in the longitudinal direction of the chassis, i.e. in different holes 12 (a-i), see Fig. 1 d.
  • By placing the sprints/axis' 13 in holes 12 that are placed more towards the front end and/or back end of the chassis 20 in the longitudinal direction e.g.
  • the spring back hardness is greater than when placing the sprints/axis' 13 in holes 12 that are placed more towards (closer to) the center of the chassis 20 in the longitudinal direction e.g. holes 12 c, d, e, f and g.
  • the hardness of the spring back functionality can also be adjusted in other ways like for example switching hardness, thickness, material or design of the spring back component 6.
  • the spring back component 6 is, in the exemplified embodiment, mounted in the lower chassis section 2 by first being pushed in through a hollow (an opening) 15 arranged in an end section of the lower chassis section 2. Subsequently, the spring back component 6 is locked in position by a stopper (a locking element) 14.
  • the stopper 14 can be any suitable design, component and/or material.
  • the upper chassis segment 1 is then placed on top of the lower chassis segment 2 with the spring back components 6 fourth contact surface 9 facing the lower chassis segment's 2 second contact surface 4.
  • the upper chassis segment 1 and the lower chassis segment 2 are then mounted together to form a functioning chassis 20 by fixating the sprints/axis' 13 in a respective hole 12.
  • the current coupling means 5 allows for a sturdier combination of a spring back and coupling functionality with a simplified adjustability compared to previously known coupling elements.
  • the coupling means 5 can be embodied in different ways but always has both a coupling and a spring back functionality. This is achieved either through one or several elements, each of which, individually or in combination, has either one or both effects.
  • the elements can be placed together or separately. Non-exhaustive examples of elements include axles, screws, bolts, springs, straps and bushings. Regardless of embodiment, the parts that enable these effects are comprised in the "coupling means".
  • the embodiments shown in the drawings are only possible embodiments of this type of coupling means and are not limiting for the scope of the present invention.
